- std:: size, std:: ssize - cppreference. com
Returns the size of the given range 1,2) Returns c size(), converted to the return type if necessary
- std::size_t - cppreference. com
std::size_t can store the maximum size of a theoretically possible object of any type (including array) On many platforms (an exception is systems with segmented addressing) std::size_t can safely store the value of any non-member pointer, in which case it is synonymous with std::uintptr_t

- std::vector lt;T,Allocator gt;::size - cppreference. com
Return value std::distance(begin(), end()) Complexity Constant Example The following code uses size to display the number of elements in a std::vector<int>:
- size_t - cppreference. com
size_t can store the maximum size of a theoretically possible object of any type (including array) size_t is commonly used for array indexing and loop counting
- sizeof operator - cppreference. com
Queries size of the object or type Used when actual size of the object must be known
- std::array lt;T,N gt;::size - cppreference. com
Run this code #include <array> #include <iostream> int main () { std::array<int, 4> nums {1, 3, 5, 7}; std::cout << "nums contains " << nums size() << " elements \n"; }
- std::vector lt;T,Allocator gt;::size - cppreference. com
Example [edit] The following code uses size to display the number of elements in a std::vector<int>: Run this code #include <cassert>#include <vector>int(){std::vector<int>;assert(size()==0);={1234};assert(size()==4);}
